Sato no Akari's song is Uptempo but also has slower parts.
Triplet's song is a rock tune.
ODATOMO's song is a ballad.
All of this is kinda expected, I think. Especially Triplet. lol
But it'll be interesting to hear Tomoko in a ballad. :0
Sato no akari, means "The light of the village" or something like that. And most likely if written in Japanese it'd be: 里の明かり。
Which would mean that it has Rina's kanji but with a different reading. Not Masaki's reading since hers is 左藤(さとう/Satou) but it can be played around with enough. :b
